Gas substitution method and device for glovebox
Description
The device of the present invention comprises (1) a gas substituting channel which allows only discharge of gases in a main body box, (2) a balloon disposed in the main body box, (3) a gas supply channel for supplying atmospheric gases to the balloon, and (4) a direction control means for connecting/switching the space in the balloon to the supply channel and the space out of the balloon in the main body box. The balloon is inflated to discharge the gases out of the balloon in the main body box from the main body box. The atmospheric gases in the balloon at which the total amount of oxygen is reduced are sent to the space out of the balloon in the main body box. The inside of the main body box is formed by the atmospheric gases having lowered oxygen concentration. This operation is repeated twice or three times. (I.S.)
